Li3Cu5O8 is Caswellsilverite-like structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six equivalent CuO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with eight CuO6 octahedra. The corner-sharing octahedra tilt angles range from 3–4°. There are four shorter (2.13 Å) and two longer (2.14 Å) Li–O bond lengths. There are three inequivalent Cu+2.60+ sites. In the first Cu+2.60+ site, Cu+2.60+ is bonded to six equivalent O2- atoms to form CuO6 octahedra that share corners with six equivalent CuO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent CuO6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Cu–O bond lengths are 2.08 Å. In the second Cu+2.60+ site, Cu+2.60+ is bonded to six equivalent O2- atoms to form CuO6 octahedra that share corners with six equivalent CuO6 octahedra, edges with six equivalent LiO6 octahedra, and edges with six equivalent CuO6 octahedra. The corner-sharing octahedral tilt angles are 4°. All Cu–O bond lengths are 2.08 Å. In the third Cu+2.60+ site, Cu+2.60+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with six equivalent LiO6 octahedra, edges with four equivalent LiO6 octahedra, and edges with eight CuO6 octahedra. The corner-sharing octahedra tilt angles range from 3–4°. There are two shorter (2.02 Å) and four longer (2.03 Å) Cu–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to three equivalent Li1+ and three equivalent Cu+2.60+ atoms to form OLi3Cu3 octahedra that share corners with six equivalent OLi3Cu3 octahedra and edges with twelve equivalent OLi2Cu4 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second O2- site, O2- is bonded to two equivalent Li1+ and four Cu+2.60+ atoms to form OLi2Cu4 octahedra that share corners with six equivalent OLi2Cu4 octahedra and edges with twelve OLi3Cu3 octahedra. The corner-sharing octahedral tilt angles are 0°.
